StoneNest End User License Agreement
Effective date: upon adoption at launch
This End User License Agreement ("Agreement") is a binding contract between StoneNest LLC, an Indiana limited liability company ("StoneNest," "Licensor," "we," "us"), and the person or business that installs, accesses, or uses the StoneNest desktop software ("you," "Licensee"). Please read it carefully.
By checking the acceptance box, installing, or using the Software, you agree to this Agreement. If you are agreeing on behalf of a company, you represent that you are authorized to bind it. If you do not agree, do not install or use the Software.
1. Definitions
Plain-English summary: the words below mean what we say they mean throughout this Agreement.
1.1 "Software" means the StoneNest Windows desktop application, in any mode (Estimator Mode, beta, trial, or licensed), including its executables, libraries, updates we make available to you, and accompanying documentation.
1.2 "Beta" or "Beta Version" means any pre-release, evaluation, or "founding-window" build of the Software distributed without charge and labeled as beta or pre-release.
1.3 "Estimator Mode" means the no-charge operating mode the Software enters whenever it is not covered by an active trial or Subscription (whether it has never been licensed, or a trial or Subscription has ended). In Estimator Mode the Software provides estimator-only functionality — manual entry of piece dimensions producing a slab count, yield estimate, and on-screen preview (equivalent to the free web estimator) — with no DXF import and no DXF export. DXF-based nesting requires an active trial or Subscription. Estimator Mode is available indefinitely and may be modified, limited, or discontinued at any time.
1.4 "Subscription" means a paid, recurring plan (billed monthly, or annually if offered) that entitles you to use the Licensed Version for as long as the Subscription remains active and in good standing.
1.5 "Licensed Version" means the Software with its full paid features (including DXF import, nesting of up to eighteen (18) unit types, and DXF export) unlocked by an active Subscription or an active trial.
1.6 "License Key" means the StoneNest-issued, cryptographically signed key (paste key and/or .snlic file) that activates the Licensed Version and carries a "paid-through" date reflecting the period your Subscription has paid for.
1.7 "Entitlement Check-in" means the automated online check-in the Software performs when it starts and about once a day while it stays running, by which it confirms your Subscription is active, refreshes the paid-through date in your License Key, learns whether an update is available, and reports the limited identity and usage information described in Section 2.5.
1.8 "Grace Period" means the thirty-five (35) day window during which the Licensed Version continues to work fully even though it has not been able to complete an Entitlement Check-in (see Section 2.5).
1.9 "Seat" means one concurrent activation of the Licensed Version, bound to one Machine at a time; "Machine" means a single physical or virtual computer identified by a device fingerprint.
1.10 "Output" means any result the Software produces, including slab counts, yield figures, nesting layouts, on-screen results, and exported files (such as DXF files).
2. License grant, subscription, and activation
Plain-English summary: while your subscription is active you get the full app (DXF import, nesting, and export); a free trial lets you evaluate it first; if you cancel or lapse, the app keeps running in Estimator Mode. Your data never leaves your machine and is never deleted — but the bid library and backup archives are stored encrypted and open through the app only while a subscription or trial is active; every DXF you exported stays an ordinary, unlocked file. One paid seat runs on one machine at a time; the app works offline day to day.
2.1 Subscription license. Subject to your payment of the applicable Subscription fees and your compliance with this Agreement, StoneNest grants you a non-exclusive, non-transferable, non-sublicensable license to install and use the Licensed Version on the number of Seats your Subscription covers, on Machines you own or control, for your internal business purposes, for as long as your Subscription is active and in good standing. This is a subscription right, not a perpetual license: when your Subscription ends, your right to run the Licensed Version ends and the Software reverts to Estimator Mode (Section 2.6).
2.2 Free trial. New users receive a 7-day, full-featured free trial that begins automatically the first time the Software runs on a Machine — no payment card, account, or activation key is required. The trial is limited to one per Machine (the Software keeps a small local record on the Machine for this purpose, which persists across uninstalls) and one per customer email via our download page. You may request a one-time self-serve extension that adds 7 more days (14 days total), delivered as a license file to your email. Any further extension requires StoneNest's approval. The trial is for internal evaluation only; on expiry the Software reverts to Estimator Mode until you start a paid Subscription.
2.3 Estimator Mode. StoneNest grants you a non-exclusive, non-transferable, revocable license to use the Software in Estimator Mode for your internal business purposes, at no charge and for as long as StoneNest offers it. Estimator Mode is feature-limited as described in Section 1.3 (manual estimator only — slab count, yield, and preview; no DXF import or export) and may be modified, limited, or discontinued at any time.
2.4 Seats and machine binding. Each paid Seat entitles you to one active installation bound to one Machine at a time. Activation associates your License Key with that Machine's device fingerprint, so that one Seat unlocks the Licensed Version on one active Machine. You may self-serve deactivate a Machine and reactivate on another (for example, when you replace a computer), subject to reasonable anti-abuse limits. For sites without internet access, a manual (air-gapped) activation path is available on request.
2.5 Entitlement Check-in and offline grace. When the Software starts, and about once a day while it stays running, it performs an automated Entitlement Check-in with stonenest.app. The Check-in happens in every mode — paid Subscriptions, free trials, and Estimator Mode alike. What a Check-in transmits is limited to: your license key identifier and license email (when a License Key exists), a one-way hash of your Machine's device fingerprint, the Software version and edition/mode, and coarse usage counts (the number of launches, bids created, nests run, and DXF exports since the last successful Check-in) — as described in the Privacy Policy. It never transmits your DXF files, layouts, dimensions, job data, customer information, or any content of your work. A Check-in is also how the Software learns that an update is available; updates install only after you confirm them in the Software (Section 2.7). The Software works offline day to day and does not require a live connection to operate; a failed or unavailable Check-in changes nothing about how the Software runs at that moment. For paid Subscriptions, if no successful Check-in occurs, the Licensed Version continues to work fully throughout a 35-day Grace Period; only if the Grace Period ends with no successful Check-in does it stop unlocking paid features and revert to Estimator Mode.
2.6 Cancellation, lapse, and reversion to Estimator Mode. You may cancel at any time. On cancellation, non-payment, or expiry of the Grace Period, the Licensed Version gracefully degrades to Estimator Mode — it does not uninstall, and your local data, settings, and files are left untouched on your Machine and are never deleted, altered, or transmitted by StoneNest. Access to Encrypted Local Data (Section 2.8) requires an active Subscription or trial. You may restore full features — including access to your Encrypted Local Data — at any time by resuming a Subscription under the same account email and completing a Check-in.
2.7 Updates. While your Subscription is active you receive the Software updates we make generally available, including major versions. When a Check-in reports that an update is available, the Software shows you an in-app notice; no update downloads or installs until you confirm it in the Software — there is no silent or background updating. Before installing, the Software verifies the downloaded package's integrity and publisher signature and refuses anything that does not verify. Updates are licensed to you under this Agreement (and, where an update is accompanied by a revised version of this Agreement, the Software asks you to accept the revised version at first run of the update — see Section 14).
2.8 Local data encryption at rest ("Encrypted Local Data"). The Software stores your bid library's structured data (bids, projects, revision records) and its backup archives on your own Machine, encrypted at rest and keyed to your license (your account email). During a first-run free trial, before any license exists, this data is keyed to the Machine instead; when you later activate a license, the Software automatically re-keys existing data to that license's email. No bid data is stored on, or transmitted to, StoneNest's servers. While your Subscription or trial is active, the Software reads and writes this data transparently, including restoring backup archives on a replacement Machine activated with the same account email. When no active Subscription or trial is present, the encrypted files remain on your Machine exactly as written, and the Software does not decrypt them until a Subscription resumes. Files the Software exports for use outside StoneNest — including every exported DXF — are not encrypted, remain ordinary files wherever you saved them, and are unaffected by Subscription status. You are responsible for maintaining access to the account email your license is issued under; contact support@stonenest.app for recovery assistance.
3. License restrictions
Plain-English summary: don't copy, resell, rent out, or reverse-engineer the Software, and don't use more seats than you subscribed for.
You will not, and will not permit any third party to:
3.1 copy the Software except for one reasonable backup copy;
3.2 sell, resell, distribute, sublicense, rent, lease, lend, or provide the Software on a service-bureau, hosting, timeshare, or SaaS basis;
3.3 use License Keys on more Seats or Machines than your Subscription covers, or share, publish, or circumvent License Keys, machine binding, the Entitlement Check-in, or any other license enforcement;
3.4 reverse engineer, decompile, or disassemble the Software, or attempt to derive its source code, except to the limited extent applicable law expressly permits despite this restriction;
3.5 modify, translate, or create derivative works of the Software;
3.6 remove, alter, or obscure any proprietary notices, disclaimers, or the estimates disclaimer described in Section 7; or
3.7 use the Software in violation of any applicable law.
4. Beta versions (pre-release)
Plain-English summary: the beta is free, unfinished, may change or break, and comes with no support promise — use it accordingly.
4.1 Pre-release nature. Beta Versions are provided for early evaluation and are pre-release, work-in-progress software. They may contain bugs, errors, and inaccuracies, may be incomplete, and may behave unpredictably.
4.2 May change or be withdrawn. StoneNest may modify, suspend, replace, or discontinue any Beta Version, or any feature of it, at any time and without notice. Features present in a Beta Version may change or be removed before or after general release, and pricing for a general release is not guaranteed by participation in the beta.
4.3 No support obligation. StoneNest has no obligation to provide support, maintenance, updates, or bug fixes for any Beta Version, and no obligation to release any general version.
4.4 No fee; disclaimers apply fully. Beta Versions are provided free of charge. The warranty disclaimer (Section 6), the estimates disclaimer (Section 7), and the limitation of liability (Section 8) apply in full to Beta Versions and Estimator Mode. Because you pay no fee for the Beta or Estimator Mode, the liability cap in Section 8 is the fixed floor amount stated there, so that the cap remains real and non-illusory rather than zero.
4.5 Unsigned builds. Early Beta Versions may be distributed as unsigned installers and may trigger operating-system warnings (for example, Microsoft SmartScreen). See the Beta Notice and the download page for honest guidance and SHA-256 verification instructions. You are responsible for verifying the integrity of any build before installing it.
5. Fees, subscription, and refunds
Plain-English summary: there's a free 7-day trial and a no-charge Estimator Mode; paid plans are monthly and you can cancel anytime; founders get a rate locked for the life of their subscription; you can get your first paid month back within 30 days.
5.1 Pricing and plans. Current pricing is published on the StoneNest website and, at time of drafting, is:
- Free trial — 7 days, full-featured, no payment card required; one self-serve extension adds 7 more days.
- Estimator Mode — $0, available indefinitely; estimator-only (manual entry → slab count, yield, and preview; no DXF import or export).
- Founders Seat — $69/month, limited to the first 25 shops; the founder rate is price-locked for the life of the Subscription (see Section 5.3). Numbered seats.
- Full Seat — $99/month once the founder seats are filled; cancel anytime.
- Annual prepay — optionally offered later, not at launch.
All prices are in US dollars and track the canonical price book; the website controls the current amounts.
5.2 Payment processor / merchant of record. Purchases and recurring billing are processed by our merchant of record, Paddle, which is the seller of record for the transaction and handles payment, invoicing, recurring charges, and applicable taxes. Your Subscription is also subject to Paddle's buyer terms.
5.3 Founder price-lock. If you subscribe as one of the numbered Founders Seats, your monthly rate will not increase for as long as you remain continuously subscribed. If your Subscription lapses for more than sixty (60) days, the founder rate is forfeited, and any re-subscription is at the then-current Full Seat price. The founder rate is a contractual commitment tied to continuous subscription; it is not a perpetual entitlement independent of the Subscription.
5.4 Automatic renewal. Paid Subscriptions renew automatically each billing period until you cancel. You may cancel at any time through the customer portal our merchant of record provides; cancellation stops future charges and, at the end of the paid period, reverts the Software to Estimator Mode.
5.5 Refunds — 30 days on the first paid month. You may request a full refund within thirty (30) days of your first paid Subscription charge, for any reason. Subsequent billing periods are non-refundable, but you may cancel at any time to stop future charges; we do not pro-rate a partial period (a "Paddle-style" policy). On refund, your License Key may be revoked and the Software reverts to Estimator Mode. This policy applies everywhere StoneNest and its merchant of record operate.
6. Disclaimer of warranties
Plain-English summary: the Software is provided "as is," with no guarantees of any kind.
TO THE MAXIMUM EXTENT PERMITTED BY LAW, THE SOFTWARE (INCLUDING ANY BETA VERSION, ESTIMATOR MODE, AND ALL OUTPUT) IS PROVIDED "AS IS" AND "AS AVAILABLE," WITH ALL FAULTS AND WITHOUT WARRANTY OF ANY KIND, WHETHER EXPRESS, IMPLIED, STATUTORY, OR OTHERWISE. STONENEST SPECIFICALLY DISCLAIMS ALL IMPLIED WARRANTIES, INCLUDING WITHOUT LIMITATION THE IMPLIED WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, TITLE, NON-INFRINGEMENT, ACCURACY, AND ANY WARRANTIES ARISING FROM COURSE OF DEALING OR USAGE OF TRADE.
STONENEST DOES NOT WARRANT THAT THE SOFTWARE WILL BE UNINTERRUPTED, ERROR-FREE, OR SECURE, THAT DEFECTS WILL BE CORRECTED, OR THAT ANY OUTPUT — INCLUDING SLAB COUNTS, YIELD FIGURES, OR LAYOUTS — WILL BE ACCURATE, COMPLETE, OR SUITABLE FOR ANY PURPOSE. NO ORAL OR WRITTEN INFORMATION OR ADVICE GIVEN BY STONENEST OR ANY THIRD PARTY CREATES ANY WARRANTY.
SOME JURISDICTIONS DO NOT ALLOW THE EXCLUSION OF CERTAIN WARRANTIES, SO SOME OF THE ABOVE EXCLUSIONS MAY NOT APPLY TO YOU.
7. Estimates disclaimer — verify Output before you rely on it
Plain-English summary: StoneNest is an estimating aid. Check every count and layout yourself before you bid, quote, buy material, or cut. We are not responsible for your bidding or purchasing decisions.
THE SOFTWARE PRODUCES NESTING LAYOUTS AND SLAB-COUNT ESTIMATES THAT ARE INTENDED SOLELY AS AN AID TO YOUR PROFESSIONAL JUDGMENT. ALL OUTPUT — INCLUDING SLAB COUNTS, YIELD FIGURES, LAYOUTS, AND EXPORTED FILES — IS AN ESTIMATE.
OUTPUT DEPENDS ENTIRELY ON THE ACCURACY OF THE INPUT FILES, DIMENSIONS, QUANTITIES, AND SETTINGS YOU PROVIDE, AND DOES NOT ACCOUNT FOR MATERIAL DEFECTS, BREAKAGE, VEIN OR PATTERN MATCHING, SLAB DIMENSIONAL VARIANCE, REMNANT AVAILABILITY, OR YOUR SHOP-SPECIFIC CUTTING PRACTICES.
YOU ARE SOLELY RESPONSIBLE FOR INDEPENDENTLY VERIFYING ALL OUTPUT — INCLUDING SLAB COUNTS, LAYOUTS, AND EXPORTED FILES — AND FOR APPLYING YOUR OWN CONTINGENCY BEFORE RELYING ON ANY OUTPUT IN ANY BID, QUOTE, MATERIAL PURCHASE, PROCUREMENT, OR FABRICATION DECISION.
STONENEST IS NOT RESPONSIBLE FOR BID OUTCOMES, QUOTES, MATERIAL PURCHASING DECISIONS, FABRICATION RESULTS, OVERRUNS, SHORTAGES, OR ANY OTHER DECISION OR RESULT BASED ON OUTPUT. THE SOFTWARE IS NOT A SUBSTITUTE FOR A QUALIFIED FABRICATOR'S REVIEW.
8. Limitation of liability
Plain-English summary: if something goes wrong, our total liability is capped at the greater of what you paid us in the last 12 months or $100, and we are never liable for lost profits or consequential damages.
8.1 No indirect damages. TO THE MAXIMUM EXTENT PERMITTED BY LAW, IN NO EVENT WILL STONENEST BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, EXEMPLARY, OR PUNITIVE DAMAGES, OR FOR ANY LOST PROFITS, LOST REVENUE, LOST OR UNDERPRICED BIDS, MATERIAL OR SLAB COSTS, COST OF SUBSTITUTE GOODS, LOSS OF DATA, LOSS OF GOODWILL, OR BUSINESS INTERRUPTION, ARISING OUT OF OR RELATED TO THIS AGREEMENT OR THE SOFTWARE, WHETHER IN CONTRACT, TORT (INCLUDING NEGLIGENCE), STRICT LIABILITY, OR ANY OTHER THEORY, AND EVEN IF STONENEST HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.
8.2 Aggregate cap. TO THE MAXIMUM EXTENT PERMITTED BY LAW, STONENEST'S TOTAL AGGREGATE LIABILITY ARISING OUT OF OR RELATED TO THIS AGREEMENT OR THE SOFTWARE WILL NOT EXCEED THE GREATER OF (A) THE TOTAL AMOUNTS YOU ACTUALLY PAID STONENEST FOR THE SOFTWARE IN THE TWELVE (12) MONTHS IMMEDIATELY PRECEDING THE EVENT GIVING RISE TO THE CLAIM, OR (B) ONE HUNDRED US DOLLARS ($100). THE $100 FLOOR ENSURES THAT USERS OF ESTIMATOR MODE AND BETA VERSIONS, WHO PAY NO FEE, ARE STILL SUBJECT TO A REAL, NON-ILLUSORY CAP.
8.3 Essential purpose. THE LIMITATIONS IN THIS SECTION APPLY REGARDLESS OF THE FORM OR THEORY OF ACTION AND EVEN IF ANY LIMITED REMEDY FAILS OF ITS ESSENTIAL PURPOSE. THEY REFLECT AN AGREED ALLOCATION OF RISK AND ARE A FUNDAMENTAL BASIS OF THE BARGAIN.
8.4 Exclusions. SOME JURISDICTIONS DO NOT ALLOW CERTAIN LIMITATIONS, SO SOME OF THE ABOVE MAY NOT APPLY TO YOU. NOTHING IN THIS AGREEMENT LIMITS LIABILITY THAT CANNOT BE LIMITED BY LAW (FOR EXAMPLE, LIABILITY FOR FRAUD OR WILLFUL MISCONDUCT).
9. Indemnification
Plain-English summary: if your use of the Software causes a third-party claim, you cover us.
You will defend, indemnify, and hold harmless StoneNest and its members, officers, and agents from and against any third-party claims, damages, liabilities, costs, and expenses (including reasonable attorneys' fees) arising out of or related to: (a) your bids, quotes, procurement, or fabrication decisions; (b) your input files, drawings, or data, including any intellectual-property claim relating to them; (c) your use of the Software in violation of this Agreement or applicable law; or (d) your misuse of the Software.
10. Intellectual property; feedback
Plain-English summary: we keep all rights in the Software; ideas you send us we can use freely.
10.1 The Software is licensed, not sold. StoneNest and its licensors retain all right, title, and interest in and to the Software, including all intellectual-property rights. No rights are granted except as expressly set out here.
10.2 The Software includes third-party open-source components governed by their own licenses; those licenses are reproduced in the THIRD_PARTY_LICENSES.txt file included with the Software.
10.3 If you provide feedback, suggestions, or ideas, you grant StoneNest a perpetual, irrevocable, royalty-free license to use them without restriction or obligation to you.
11. Term and termination
Plain-English summary: your paid rights last while your subscription is active; breaking the rules ends your license; Estimator Mode and the protective terms survive.
11.1 This Agreement is effective until terminated. Your right to use the Licensed Version continues while your Subscription (or trial) is active and in good standing (Section 2). This Agreement terminates automatically if you materially breach it (for example, by sharing or circumventing License Keys or the machine-binding or check-in enforcement).
11.2 On expiry, cancellation, non-payment, or non-renewal of your Subscription, the Software reverts to Estimator Mode (Section 2.6). On termination for your material breach, you must stop using the Licensed Version, and Estimator Mode may also be terminated for that breach.
11.3 Sections 1, 3, and 6 through 15 survive termination. Reversion to Estimator Mode at the end of a Subscription (Section 2.6) is not itself a termination of this Agreement and does not affect your continued use of the Software under Estimator Mode.
12. Export and sanctions compliance
Plain-English summary: you confirm you're allowed to receive the Software under US export and sanctions law.
You represent that you are not located in, and are not a national of or ordinarily resident in, any country or region subject to comprehensive US embargo, and that you are not on any US government restricted- or denied-party list. You will comply with all applicable US export-control and sanctions laws in your use of the Software.
13. Governing law and dispute resolution
Plain-English summary: Indiana law governs. Talk to us first to try to resolve any dispute informally. The exact court venue and dispute-resolution process are still being finalized for the adopted version of these terms.
13.1 Governing law. This Agreement is governed by the laws of the State of Indiana, without regard to its conflict-of-laws rules. The UN Convention on Contracts for the International Sale of Goods does not apply.
13.2 Informal resolution first. Before starting any formal proceeding, you agree to first contact StoneNest at support@stonenest.app with a written description of the dispute and to work in good faith to resolve it. If it is not resolved within sixty (60) days, either party may proceed as described below.
13.3 Class-action waiver. TO THE EXTENT PERMITTED BY LAW, EACH PARTY WAIVES ANY RIGHT TO PARTICIPATE IN A CLASS, COLLECTIVE, OR REPRESENTATIVE ACTION.
13.4 Venue and dispute-resolution process. The governing law, venue, and dispute-resolution process will be finalized in the adopted version of these terms.
14. Changes to this Agreement
Plain-English summary: new versions apply to new purchases and continued use; the version you accepted governs what you already bought.
StoneNest may update this Agreement for future releases and purchases. The version you accept at purchase or first run governs that transaction and your use of the Software; material changes will be posted on the StoneNest website with an updated effective date. When a Software update carries a revised version of this Agreement, the Software presents the revised Agreement in-app the first time the updated Software runs, and asks you to accept it before continuing — you are never bound to a revision you have not been shown. Your continued use of the Software after accepting a change constitutes acceptance of the updated Agreement for that use.
15. General
Plain-English summary: standard closing terms.
15.1 Entire agreement. This Agreement is the entire agreement between you and StoneNest regarding the Software and supersedes all prior understandings on that subject.
15.2 Severability. If any provision is held unenforceable, the rest remains in effect and the unenforceable provision is enforced to the maximum extent permitted.
15.3 No waiver. Failure to enforce any provision is not a waiver of it.
15.4 Assignment. You may not assign this Agreement without StoneNest's consent. StoneNest may assign it, including in connection with a sale of its business.
15.5 Notices. Notices to you may be given by email or in-app; notices to StoneNest must be sent to the address below.
15.6 Force majeure. Neither party is liable for delays or failures caused by events beyond its reasonable control.
15.7 Contact. StoneNest LLC, 3250A West 86th St #1213, Indianapolis, IN 46268
